Description

The present invention relates to a hanging jig.

When constructing a building, it is common to lift square steel pipes, shaped steel materials, sashes, and other construction members that form pillars and beams with a crane or the like, and workers install the construction members in a specified position while they are being lifted. applied.

There are various forms of hanging jigs. As an example, a tightening bolt with a handle is attached to the metal piece containing the construction member so that it can move freely relative to the metal piece. There is a lifting jig of a form in which a construction member is held by fitting it to the width of the construction member, and a metal piece is hoisted via a wire or a belt to lift the construction member.

However, with such a lifting jig that fits the width of the load by turning the handle, it takes time and effort to clamp the load by turning the handle, making it difficult to carry out efficient load lifting work. Can not. Furthermore, if the handle is tightened too tightly, concentrated tightening force from the tip of the shaft-shaped tightening bolt acts on the suspended load, which is undesirable because it may damage the suspended load.

As another example of the lifting jig, a pulley portion having a first groove and a second groove formed thereon is provided, the pulley portion is suspended by the main wire, and the first wire and the second wire are stretched over the first groove. A wire part consisting of a second wire that is stretched over two concave grooves, a first attachment part for attaching the first wire, a second attachment part for attaching the second wire, and both ends of the first wire and the second wire, respectively. A lifting jig has been proposed that has a pair of attached fasteners. In this lifting jig, the axis of the pulley and the straight line connecting the first mounting portion and the second mounting portion are separated in parallel, and the separation width between the first mounting portion and the second mounting portion is the same as that of the first concave groove. It is formed to be larger than the interval width of the second concave groove. A temporary jig is attached to the suspended load, and the suspended load is lifted by locking the connecting wire to the temporary jig and the locking device (see, for example, Patent Document 1).

JP 2009-73593 A

In the lifting jig described in Patent Document 1, the temporary jig must be attached to the suspended load in order to lift the suspended load, and the temporary jig must be removed from the suspended load after lifting. Therefore, the time and effort required for lifting is the same as in the example of the lifting jig described above. As described above, although lifting jigs are frequently used when lifting a load, there is a problem that there are many forms that require time and effort when lifting.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a lifting jig capable of efficiently lifting a load.

In order to achieve the above object, one aspect of the hanging jig according to the present invention is
Having a first member, a second member to which the belt is attached, and a fastener for tightening the belt,

The belt is attached to the fourth piece, and an engaged portion that engages with the engaging portion is provided on the third piece, and the engaged portion engages with the engaging portion. By being guided, the third piece is slidable along the second piece,
The suspended load is sandwiched between the first piece and the fourth piece.

According to this aspect, both the first piece of the first member and the fourth piece of the second member sandwich and fix the suspended load, thereby imparting a concentrated tightening force to the suspended load. This eliminates the possibility of damage to the suspended load due to concentrated clamping force. Here, there are various forms of the engaging portion provided on the second piece and the engaged portion provided on the third piece. For example, the engaging portion provided on the second piece is a ridge extending in the horizontal direction, and the engaged portion provided on the third piece is a groove that engages with the ridge. Alternatively, the engaging portion may be a horizontally extending groove, and the engaged portion may be a ridge that engages with the groove.

The belt attached to the fourth piece is inserted through the first slit and extends to the back side of the second piece, and is inserted through the second slit to extend the suspended load on the front side of the second piece. It is characterized by extending to the side on which it is arranged.

According to this aspect, the belt attached to the fourth piece is inserted through the first slit and extends to the back side of the second piece, and is inserted through the second slit to distribute the suspended load on the front side of the second piece. By extending to the side where the belt is provided, a state in which the suspended load is sandwiched between the first piece and the fourth piece can be formed without interference between the belt and the suspended load.

Further, in another aspect of the hanging jig according to the present invention, the first slit is opened in the second piece at the boundary with the first piece,
A groove into which the belt is fitted is formed at the tip of the third piece.

According to this aspect, the first slit is formed at the boundary between the second piece and the first piece, and the groove in which the belt is fitted is formed at the tip of the third piece. When the first piece and the fourth piece sandwich a suspended load while being in contact with one piece, the belt is crushed and damaged by the tip of the fourth piece and the first piece.

Another aspect of the hanging jig according to the present invention is characterized in that the belt is detachably attached to the fourth piece.

According to this aspect, since the belt is detachably attached to the fourth piece, when the belt deteriorates, the belt can be easily removed and quickly replaced with a new belt. . For example, a stopper is attached to the back surface of the fourth piece (the surface that does not sandwich the suspended load), and one end of the belt is fixed by this stopper during normal use of the lifting jig, and is provided on the fourth piece. A belt is inserted through the slit into the first slit of the second piece and extends to the rear side of the second piece.

As can be understood from the above description, according to the lifting jig of the present invention, a load can be lifted efficiently.
